Facebook Share Button - Issue

I am using The Real Design for Joomla 3 and my problem is that when I am trying to share my website's content on Facebook, I am getting a 404 error if the selected language is not the default.

I don't know if this is a template issue or Facebook issue.

You can test the facebook share button here: http://webartworld.com/el/%CF%80%CE%BF% ... F%84%CE%B5
(click on facebook share button under the article)

Thanking you in advance,

The problem is with your custom national letters. Usually they are not allowed in url's and fb sharing has problem with generating correct url.
It uses:
http://webartworld.com/el/-
instead of correct url.

Thanks a lot for your answer!

I would always suggest to use standard unicode letters (those available on each keyboard directly). Doing so assures that anybody will be able to use the page.
